1.0 General

1.1 Equipment Description

The 2016-10 Downconverter converts 500 to 1000 MHz to 200 ± 55 MHz in 1 MHz steps with low group delay

and flat frequency response. Synthesized local oscillators (LO) provide frequency selection. Multi-function

push button switches select the input frequency, gain, and other parameters. Front panel LEDs provide

indication of DC power, PLL alarm or Remote operation. Gain is adjustable manually (MGC) over a 0 to 50 dB

range. The frequency and gain are remotely selectable. Parameter selection and frequency and gain settings

appear on the LCD display. Connectors are BNC female for the RF, and BNC female for the IF and optional

external 10 MHz reference input and output (option E). Other connector options are available. The 2016-10 is

2.0 Installation

2.1 Mechanical

The 2016-10 consists of one RF/Controller PCB housed in a 1 RU (1 3/4 inch high) by 16 inch deep chassis. A

switching, ±12, +24, +5 VDC power supply provides power for the assemblies. The 2016-10 can be secured to

a rack using the 4 holes on the front panel. Figure 2.1 shows how the 2016-10 is assembled.

2.4 Operation

2.4.1 Installing and Operating the 2016-10 Downconverter

1. Connect a -55 dBm to -5 dBm signal to RF IN, J2 (Figure 2.2)

2. Connect the IF OUT, J1, to the external equipment

3. Connect 100-240 ±10% VAC, 47 - 63 Hz to AC on the back panel.

4. Set the input frequency (See Section 2.5 Menu Settings).

5. Set the gain for 0 to +50 dB (See Section 2.5 Menu Settings).

6. Be sure DS6 (green, DC Power) is on and DS3 (red, Alarm) is off (Figure 2.3).

7. AC Fuse - The fuse is a 5 mm X 20 mm, 2 amp slow blow (Type T) and is inserted in the far slot

in the drawer below the AC input as shown in Figure 2.4. There is a spare fuse in the near slot.

If a fuse continues to open, the power supply is most likely defective.

2.5 Menu Settings

2.5.1 Functions

This section describes operation of the front panel controls. There are three operator switches, the LCD

display and alarm indicator LEDs. All functions for the equipment are controlled by these components.

The functions are (see Figure 2.5):

Power Up

Normal Display

Menu 1 Frequency in MHz

Menu 2 Gain (0 to +50)

Menu 3 Set Unit to Remote Operation

Menu 4 Select External 10 MHz Ref

Menu 5 Set Remote mode (option Q)

Menu 6 Set RS-485 address (option Q)

Save Menu When “R” is selected in any above menu or at the end of the menu options

Alarm indications appear on the LEDs (see figure 2.3).

All program changes must start with the operation of the Menu/Execute switch and must also end with the

operation of the Menu/Execute switch verified by the “Save Settings?” Menu. If this sequence is not followed,

none of the changes will take effect. If programming is initiated and no operator action takes place for

approximately 30 seconds (before the final press of the Menu/Execute switch) the display will revert to its

previous status and you will need to start over.

2016-10 Manual Page 10 3/06/2008

2.5.2 Power On Settings

NOTE: THE LAST STATUS OF A UNIT IS RETAINED EVEN WHEN POWER IS REMOVED.

WHEN POWER IS RESTORED, THE UNIT WILL RETURN TO ITS PREVIOUS SETTINGS.

When power is first applied, the LCD display goes through three steps.

1. The LCD goes black to show all segments are functioning.

2. The software version will be displayed.

REV 1.00

3. The present frequency and gain of the downconverter is shown.

F = 875 G = +30

The unit is now operational and ready for any changes the operator may desire.

2.5.3 Control Switches

1. Menu/Execute - Any change to the programming of the unit must be initiated by pressing the

Menu/Execute switch and completed by pressing the Menu/Execute switch.

2. Horizontal Switch - This switch is mounted so its movement is horizontal and moves the cursor left or

right.

3. Vertical Switch - This switch is mounted so its movement is vertical and has two functions:

a. During frequency, gain changes, the vertical movement will raise or lower the number in the

direction of the arrows.

b. For other functions such Mute on/off, the vertical switch will alternately turn the function on or

off regardless of the direction operated.

2016-10 Manual Page 11 3/06/2008

2.5.4 Frequency Changes

At any time during the modification process, if you have made a mistake and do not wish to save the changes

you have made, do not press the Menu/Execute switch; simply do nothing for approximately 30 seconds,

and the system will return to the normal operating mode or scroll to “R” and push the menu/Execute switch and

select “NO” in the “SAVE SETTINGS?” window.

To change the FREQUENCY:

Operate the Menu/Execute switch until you get to the menu item you want to change see Figure 2.5 for the

sequence of menu options. The following display is for changing the downconverter frequency:

F = 875 R

Pressing the Up/Down switch down will toggle the display to:

F = 885 R

By using the horizontal rocker switch the cursor can be moved left or right .

F = 885R

NOTE: CHANGES DO NOT TAKE PLACE ON FREQUENCY UNTIL YOU GO TO THE SAVE

MENU AND INDICATE YOU WANT TO SAVE THE CHANGES.

When the display indicates the value desired you can push the Menu/Execute switch to get to the next item:

G = +30 R

OR you can scroll to “R”, push the Menu/Execute switch to get to:

SAVE SETTINGS? Y N

Selecting Y will save the new settings. Selecting N will revert to the previous settings.

Pushing the Menu/Execute switch then takes you to this:

F = 885 G = +30

Figure 2.5 gives the menu items and how to make changes.

2016-10 Manual Page 12 3/06/2008

2.5.5 Gain Changes

When you get to this menu note that the gain changes will be made as you make them but if you do not wish to

save the changes you have made, scroll to “R” and push the Menu/Execute switch and select “NO” in the

“SAVE SETTINGS?” window or do not press the Menu/Execute switch; simply do nothing for

approximately 30 seconds, and the system will return to the normal operating mode.

To change the GAIN:

Push the Menu/Execute switch to get to the gain setting (See Figure 2.5 for the sequence of menu options):

G = +30 R

Pressing the Up/Down switch will change the gain in 1 or 10 dB steps depending on the cursor location:

G = +40 R

By using the horizontal rocker switch the cursor can be moved left or right. Pressing the Up/Down switch

will toggle the display digit selected until you have the desired gain.

G = +40R

NOTE: THE GAIN WILL BE CHANGED AS YOU ADJUST THE NUMBERS. HOWEVER, THE

VALUE WILL NOT BE STORED UNTIL YOU INDICATE YES IN THE SAVE SETTINGS

WINDOW.

When the display indicates the value desired you can push the Menu/Execute switch to get to the next item:

REMOTE OFF R

OR you can scroll to “R” and push the Menu/Execute switch to get to:

SAVE SETTINGS? Y N

Selecting Y will save the new settings. Selecting N will revert to the previous settings. Pushing the

Menu/Execute switch then takes you to this:

F = 885 G = +40

Figure 2.5 gives the menu items and how to make changes.

2016-10 Manual Page 13 3/06/2008

2.5.5 Alarm Indications

An alarm condition for will occur if any local oscillator phase lock loop (PLL) comes out of lock. The Mute

LED will light if you select Mute and the Remote LED will light when you select the Remote mode.

3.0 Environmental Use Information

A. Rack-Mounting - To mount this equipment in a rack, please refer to the installation instructions

located in the user manual furnished by the manufacturer of your equipment rack.

B. Mechanical Loading - Mounting of equipment in a rack should be such that a hazardous condition

does not exist due to uneven weight distribution.

C. Elevated Operating Ambient Temperature - If installed in a closed or multi-unit rack assembly,

the operating ambient temperature of the rack may be greater than room ambient temperature.

Therefore, consideration should be given to Tmra.

D. Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow

required for safe operation of the equipment is not compromised. Additional space between unit

may be required.

E. Circuit Overloading - Consideration should be given to the connection of the equipment to the supply

circuit and the effect that overloading of circuits could have on over current protection and supply wiring.

Appropriate consideration of equipment name plate rating should be used, when addressing this concern.

F. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.

Particular attention should be given to supply connections other than direct connection to the

Branch (use of power strips).

G. Top Cover - There are no serviceable parts inside the product so, the Top Cover should not be removed.

If the Top Cover is removed the ground strap and associated screw MUST BE REINSTALLED

prior to Top Cover screw replacement. FAILURE TO DO this may cause INGRESS and/or EGRESS

emission problems.
